Abstract
414 Background: Nivolumab has shown efficacy and acceptable safety in 2 open-label, multicenter studies (CheckMate 032 and 275) and is approved for patients (pts) with metastatic urothelial carcinoma (mUC) after ≥1 platinum-based therapy. Here we report longer-term efficacy and safety results for pts with mUC in the phase 1/2 CheckMate 032 study who received nivolumab monotherapy based on > 2 years of follow-up. Methods: Pts with mUC, regardless of programmed death-1 ligand 1 (PD-L1) expression status, received nivolumab 3 mg/kg intravenously every 2 weeks until progression or discontinuation. Tumor PD-L1 membrane expression was assessed with Dako PD-L1 immunohistochemical staining. Primary endpoint: objective response rate (ORR; RECIST 1.1); other endpoints: safety, progression-free survival (PFS), overall survival (OS), and duration of response. Results: Of 78 treated pts (median age 65.5 years; range, 31-85), 52 (66.7%) had received ≥2 prior therapies. At a minimum follow-up of 24 months, 11 pts (14.1%) remain on treatment. Treatment discontinuation was mainly due to disease progression (52 pts [66.7%]). Tumor PD-L1 expression was evaluable in 68 pts (87.2%); 26 (38.2%) pts had ≥1% and 42 (61.8%) had < 1% expression. The table shows overall efficacy. Updated ORR was 25.6%, with 1 additional complete response (CR) achieved for a CR rate of 8%. Median duration of response was not reached. ORR, 1- and 2-year PFS and OS rates were similar between the PD-L1 < 1% and > 1% subsets. Grade 3 or 4 treatment-related adverse events (TRAEs) occurred in 22 pts (28.2%); most frequent were ↑lipase (6.4%), ↑amylase (5.1%), and maculopapular rash (3.8%). One pt had a grade 5 TRAE (pneumonitis). Conclusions: Nivolumab showed clinically meaningful, durable efficacy with promising long-term survival regardless of PD-L1 expression, and no new toxicity signals with longer-term follow-up in previously treated pts with mUC. Clinical trial information: NCT01928394. [Table: see text]

Abstract
169 Background: Single-agent durvalumab is being evaluated in patients with advanced squamous and non-squamous NSCLC in an ongoing Phase 1/2 study (NCT01693562). Here we present updated survival and safety data in NSCLC patients. Methods: Treatment-naïve (1L) and previously treated (2L or 3L+) stage IIIB/IV NSCLC patients received durvalumab 10 mg/kg Q2W for up to 12 months. Patients were stratified by tumor PD-L1 expression (Ventana PD-L1 [SP263] Assay [PD-L1 high: ≥25% of tumor cells with membrane staining]), treatment line, and histology. Results: As of 05 September 2017, 304 NSCLC patients received durvalumab monotherapy. Median duration of follow-up was 35.6 (0.3–50.9) months. Investigator-assessed ORR ranged between 23.2% and 30.0% among PD-L1 high patients, and between 3.6% and 8.3% among PD-L1 low/negative patients. Median PFS and median OS were longer in PD-L1 high vs PD-L1 low/negative patients (Table). Any-grade treatment-related AEs (TRAEs) were reported in 57.2% of pts (including fatigue, 17.4%, decreased appetite, 9.2%, diarrhea, 8.9%); in 10.2% of pts these were Grade 3 or 4. TRAEs resulting in treatment discontinuation were reported in 17 patients (5.6%); 1 patient had a Grade 5 TRAE (pneumonia). Conclusions: In this ongoing phase 1 study, OS and safety profile appear encouraging in treatment-naïve and previously treated NSCLC patients, particularly among PD-L1 high patients. Further investigation regarding PD-L1 expression for selection of patients who most likely benefit from durvalumab is needed. Clinical trial information: NCT01693562. [Table: see text]

Abstract
211 Background: Immunotherapies have significantly improved cancer outcomes across multiple tumor types, while concurrently introducing new and unique toxicities, requiring timely recognition and intervention. To advance physician knowledge of imAEs, an educational online platform was developed for use by AstraZeneca clinical trial investigators (PIs). Herein, we report the impact of this educational strategy on PIs’ knowledge and confidence in recognizing and managing imAEs. Methods: The web-based learning platform included 8 structured and interactive modules (mode of action, colitis, pneumonitis, rash, hepatitis, endocrinopathy, neurotoxicity and nephritis), each containing 3 lessons reviewing background, pathophysiology and diagnosis of individual imAEs, management strategies and expert videos. Pre- and post-training questions to test knowledge (n = 5) and confidence (n = 2) were offered. The platform launched in May 2016 and remains active. PIs participating in durvalumab and/or tremelimumab clinical trials are eligible for participation. Results: As of Jan 19 2017, 2372 PIs have been invited to participate, 356 accessed the platform, and 294 completed ≥1 lesson (57% mode of action, 62% colitis, 42% pneumonitis, 20% rash, 24% hepatitis, 18% endocrinopathy, 19% neurotoxicity, 15% nephritis). Although an overall high proportion of correctly answered questions was identified at the pre-training stage (73% of 2935 total questions, n = 169 PIs), accuracy increased by a mean of 11% (range -3‒27%) at the post-training stage (84%). In each module, there was ≥1 question (range 1‒3) for which correct answers increased by ≥15% post- vs pre-training. Overall, after learning, confidence levels in recognition and management of imAEs increased by 28% (57 to 85%, p < 0.05; n = 35‒102 PIs) and 28% (51 to 79%, p < 0.05; n = 28‒101 PIs), respectively. Conclusions: The number of PIs completing ≥1 lesson indicates a desire for imAE training. This educational initiative enhanced knowledge, and among PIs with suboptimal confidence pre-training, 1 in 2 reported increased confidence in imAE recognition and management, which may improve patient care and maximize treatment potential.

Abstract
e23090 Background: Nivolumab and pembrolizumab treatment targeting the PD1/PD-L1 axis has demonstrated increased survival benefit in subpopulations of patients with advanced non-small cell lung cancer (NSCLC). The impact of these therapeutics on tumor immune microenvironment is not fully understood. Classical M1 macrophages are critical components involved in the inflammatory response and antitumor immunity. In this study, we evaluated the effect of PD1/PD-L1 blockade on M1 polarization of tumor-associated macrophages (TAMs) and activation of cytotoxic T-cells in a 3D ex vivo system of NSCLC. Methods: Fresh tumor tissues obtained from consented patients with NSCLC at the time of surgical resection were utilized in a 3D ex vivo tumor miscrosphere assay. 3D tumor microspheres were treated with nivolumab or pembrolizumab at 10 mg/ml for 36 hours within an intact tumor microenvironment. Flow cytometry analysis was performed to evaluate treatment-mediated TAM polarization, activation of T-cells and changes in CD4 and CD8 subpopulations. A multiplex human cytokine assay was used to simultaneously analyze the differential secretion of cytokines. Additionally, a NanoString platform containing probes to quantitate 770 immune function genes was used to determine potential positive or negative associations between expression of immune function genes and TIL activation by ex vivo treatment. Results: Both nivolumab and pembrolizumab treatment increased population of M1 macrophages (CD68+, CD80+, CD163-) and simultaneous release of MIP1b, IFN-ɣ, TNF-a, and GM-CSF cytokines as well as expression of genes related to the M1 phenotype that was accompanied by activation of CD8 cells assessed by Ki67 and CD107a expression and increased expression of genes involved in the IFNg pathway. Conclusions: Our studies showed that anti PD1/PD-L1 treatment leads to M1 macrophage polarization and T-cell activation in subgroups of NSCLC patients emphasizing the importance of comprehensive analysis of tumor immune microenvironment for a better understanding of the mechanism of action of immuno-oncology drugs that may help developing rationale combination treatments in NSCLC.

Abstract
e20672 Background: WEE1, a dual serine/threonine and tyrosine kinase involved in regulation of the G2/M cell cycle checkpoint, is an essential component for proper DNA damage response. In combination with platinum agents, the inhibition of WEE1 is expected to lead to unstable DNA replication structures, inability to repair DNA damage, loss of G2/M arrest and ultimately mitotic catastrophe. In NSCLC cell lines, we previously demonstrated that cisplatin exhibited enhanced effects in combination with AZD1775 (a WEE1 inhibitor). This trial tests AZD1775 combined with a platinum doublet in patients with sqNSCLC. Methods: In this single-arm phase II trial, patients with stage IV sqNSCLC receive intravenous (IV) carboplatin AUC 5, IV paclitaxel 175 mg/m2, and oral AZD1775 225 mg twice/day for 2.5 days every 21 days for 4-6 cycles followed by maintenance AZD1775 at the same doses. Antiemetics prior to each dose of AZD1775 are mandatory. The primary endpoint is response rate per RECIST v1.1, with overall and progression-free survival as secondary endpoints. Archival tissue specimens are collected for correlative analyses of p53, PAXIP1, and WEE1. Results: Interim analysis of the 15 patients [3/15 (20%) female] enrolled through 11/2016 show 14/15 (93%) were ECOG 1, and 1/9/5 (7%/60%/33%) were never/former/current smokers. The most frequent adverse events of any grade were diarrhea (53%), nausea (40%), and vomiting (33%). The 2 most common grade 3-4 adverse events were neutropenia (13%) and fatigue (20%). No patients required treatment discontinuation due to toxicity. Of the 10 patients evaluable for response, 3 (30%) had confirmed partial responses (PR), 1 (10%) had unconfirmed PR, 5 (50%) had stable disease (SD), and 1 (10%) had progressive disease for a disease control rate of 90%. In those with SD, tumors regressed by -15%, -22%, -23%, -26% and -28% at first scan. Conclusions: AZD1775 combined with carboplatin and paclitaxel is tolerable and demonstrates promising activity in advanced sqNSCLC patients. Nausea and vomiting are manageable with antiemetics. The study continues to enroll. Correlative biomarker analyses of the tissue are planned. More mature data will be presented. Clinical trial information: NCT02513563.

Abstract
8503 Background: Patients (pts) with advanced SCLC after first-line platinum-based chemotherapy (PLT-CT) have a poor prognosis and limited treatment options. CheckMate 032 is a phase I/II trial evaluating multiple regimens of nivo ± ipi in solid tumors, including advanced SCLC. Tolerability and efficacy of nivo ± ipi were demonstrated in early results from the initial treatment arms (Antonia, Lancet Oncol 2016), prompting long-term follow-up and the addition of a randomized expansion cohort to further evaluate nivo ± ipi in advanced SCLC. Methods: In the initial treatment arms, pts with advanced SCLC and disease progression after prior PLT-CT were assigned to nivo (3 mg/kg Q2W; n = 98) or nivo 1 + ipi 3 (1 mg/kg and 3 mg/kg Q3W x 4, then nivo 3 Q2W; n = 61); safety/efficacy was assessed with a follow-up of ~18 mo. In the subsequent SCLC expansion cohort, pts were randomized 3:2 to nivo vs nivo 1 + ipi 3 and stratified by number of prior therapies. The primary endpoint was objective response rate (ORR). Results: Updated efficacy/safety results from the initial (non-randomized) nivo and nivo 1 + ipi 3 arms are summarized in the table. Responses were durable and occurred regardless of PD-L1 expression or PLT-sensitivity; safety was consistent with prior nivo ± ipi studies. In the expansion cohort, 247 pts were randomized to nivo or nivo 1 + ipi 3. The presentation will contain the first report of efficacy/safety results and subgroup analyses from this randomized expansion cohort. Conclusions: Durable responses are observed with nivo and nivo + ipi in pts with previously treated SCLC. The expansion cohort represents the first randomized evaluation of combined immune checkpoint blockade in SCLC. Clinical trial information: NCT01928394. [Table: see text]

Abstract
4071 Background: Durvalumab, an anti-PD-L1 mAb, has shown early and durable clinical activity with manageable safety in an ongoing Phase 1/2, multicenter, open-label study in pts with advanced solid tumors. Interim analyses from the HCC cohort in the dose-expansion part of this study are reported here. Methods: Patients with HCC (Child-Pugh class A) received durvalumab 10 mg/kg i.v. q2w for 12 months or until confirmed progressive disease, whichever occurred first. The primary objective was to evaluate the safety profile; secondary objective was to assess the antitumor activity (investigator-assessed RECIST v1.1). Clinical activity was evaluated for the total HCC population and by viral status. Results: As of Oct 24 2016, 40 HCC pts with median 23.9 (range 2.4–34.7) weeks follow-up received durvalumab. 93% had prior sorafenib. Treatment-related AEs occurred in 80.0% of pts, most commonly fatigue (27.5%), pruritus (25.0%) and elevated aspartate aminotransferase (AST) (22.5%). Grade 3–4 treatment-related AEs were reported in 20.0% of pts, most commonly elevated AST (7.5%) and elevated alanine aminotransferase (5.0%). 7 (17.5%) pts completed the initial 12-month treatment and 7 (17.5%) pts discontinued treatment because of an AE (none related to treatment). There were no deaths due to treatment-related AEs. Clinical activity is presented in the table. 4 pts achieved a PR; 2 were ongoing at data cut-off. Conclusions: Durvalumab had an acceptable safety profile and showed promising antitumor activity and OS in pts with HCC, particularly HCV+ pts. Clinical trial information: NCT01693562.

Abstract
e23091 Background: Bavituximab is a chimeric monoclonal antibody that targets the membrane phospholipid phosphatidylserine (PS) exposed on endothelial cells and cancer cells in solid tumors. Our previous studies showed that bavituximab enhances the activation of CD8+ TILs that correlates with increased cytokine production by lymphoid and myeloid cells in lung cancer with low PD-L1 expression suggesting that the interruption of the PD-1/PD-L1 axis by nivolumab may enhance the bavituximab effect in tumors. Methods: Fresh tumor tissues obtained from consented patients with NSCLC at the time of surgical resection were utilized in a 3D ex vivo tumor miscrosphere assay, where 3D tumor microspheres were treated with bavituximab or nivolumab alone or in combination at 10 mg/ml for 36 hours. At the end of the treatment, a multiplex human cytokine assay was used to simultaneously analyze the differential secretion of cytokines, including human IFNg, in culture media as a surrogate of TIL activation. In addition, a gene expression analysis using a NanoString platform containing probes to quantitate 770 immune function genes. Results: Preliminary results indicate the combination treatment with bavituximab and nivolumab led to increased expression of genes involved in M1 polarization of tumor associated macrophages in a subpopulation of lung tumors that closely correlated with release of cytokines such as MIP1b (CCL4) which is a chemoattractant for natural killer cells, monocytes and a variety of other cells involved in tumor immune response. Conclusions: This lung patient derived ex-vivo approach indicates that bavituximab in combination with nivolumab may enhance immune response. This response likely involves M1 polarization of tumor associated macrophages and suggests potential clinical implications in the treatment of lung cancer.

Abstract
e20504 Background: Single-agent durvalumab demonstrated manageable safety and encouraging clinical activity in advanced squamous and non-squamous NSCLC in preliminary analyses from the Phase 1/2 1108 study (NCT01693562). Here we present updated safety data and clinical activity in NSCLC pts with no prior treatment for advanced disease. Methods: In this Phase 1/2 dose-escalation and expansion study, pts with Stage IIIB/IV NSCLC, ECOG PS 0–1, and availability of a fresh tumor biopsy and/or archival tumor tissue for PD-L1 testing received durvalumab 10 mg/kg every 2 weeks for up to 12 months, with retreatment permitted for those progressing after 12 months of therapy. Tumor PD-L1 expression was assessed using the Ventana PD-L1 (SP263) Assay (PD-L1 high: ≥25% of tumor cells with membrane staining). Results: As of 24 October 2016, 59 pts (63% ECOG PS 1, 49% squamous) received first-line durvalumab. Median duration of follow-up was 17.3 (1.0–36.8) mos. Safety profile was consistent with the overall (N = 304, ≥0 prior lines of therapy) NSCLC cohort. All-grade treatment-related adverse events (AEs) were reported in 56%; the most common were fatigue (15%), diarrhea (13%), and decreased appetite (10%). 7% had a treatment-related AE leading to discontinuation of durvalumab, including diarrhea in 2 pts. Grade ≥3 treatment-related AEs (all n = 1) occurred in 10%; 1 pt died due to drug-related pneumonia. 49 pts had high PD-L1 expression and 9 pts had low/negative PD-L1 expression; data are not summarized for the latter group due to the small number of pts. For the PD-L1 high subpopulation, confirmed ORR (investigator-assessed RECIST v1.1) was 28.6% (95% CI 16.6–43.3) and disease control rate (stable disease ≥24 weeks) was 42.9% (95% CI 28.8–57.8); median PFS was 4.0 months (95% CI 2.3–9.1), median OS was 21.0 months (95% CI 14.5–not estimable), and 12-month OS rate was 72% (95% CI 56–83). Response rates were similar and durable regardless of histology. Conclusions: Consistent with prior data, durvalumab had a tolerable safety profile in advanced treatment-naïve NSCLC. Clinical activity was seen in PD-L1 high pts, with encouraging OS. Clinical trial information: NCT01693562.

Abstract
9085 Background: Preliminary analyses of an ongoing Phase 1/2 study of single-agent durvalumab showed antitumor activity and a tolerable safety profile in advanced NSCLC, with higher ORR and longer OS in pts with high vs. low/negative PD-L1 tumor expression. Here we present updated safety analyses (primary endpoint) for all NSCLC pts and clinical activity based on investigator-assessed RECIST v1.1 in pts who had received prior treatment for advanced NSCLC. Methods: Durvalumab (10 mg/kg q2w) was given until unacceptable toxicity or disease progression, or for up to 12 mos; retreatment was permitted upon disease progression after completion of 12 mos of treatment. PD-L1 expression was assessed using the Ventana PD-L1 (SP263) Assay (PD-L1 high = ≥25% and PD-L1 low/negative = <25% of tumor cells with membrane staining). Results: As of 24 Oct 2016, 245 pts with previously treated NSCLC (53% squamous) received durvalumab and were followed for a median of 29.2 (range 0.3–40.5) mos; 142 pts (58%) had treatment-related adverse events (AEs), most frequent: fatigue (18%), decreased appetite (9%), and nausea, rash, and diarrhea (each 8%). 25 pts (10%) had treatment-related Grade 3/4 AEs, most frequent: fatigue and hyponatremia (each 2%); there were no treatment-related deaths. 4% had treatment-related serious AEs including colitis and pneumonitis (each 2%). In the overall population, 12 mo OS rate was 47% (95% CI 40–53) and 18 mo OS rate was 38% (95% CI 31–45). Antitumor activity and survival by PD-L1 status are shown in the table. Conclusions: Consistent with earlier reports, durvalumab had a manageable safety profile in Stage IIIB/IV NSCLC, with encouraging clinical activity as 2L+ therapy. Higher tumor PD-L1 expression enriched clinical benefit of response rate and survival endpoints. Clinical trial information: NCT01693562. [Table: see text]

Abstract
9093 Background: The fully human anti–PD-1 antibody N offers long-term OS benefit in patients (pts) with previously treated adv NSCLC. Adding I (anti–CTLA-4 antibody) to N has been shown to improve clinical activity vs either agent alone in multiple tumor types. We present long-term data for 1L N+I treatment of pts with adv NSCLC from CheckMate 012. Methods: In two cohorts in this phase 1 study, pts with recurrent stage IIIb/IV, chemotherapy-naive NSCLC and ECOG PS 0–1 received N 3 mg/kg Q2W combined with I 1 mg/kg Q12W (n=38) or Q6W (n=39) until disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was safety and tolerability. Secondary endpoints included investigator-assessed ORR (RECIST v1.1) and PFS. Exploratory endpoints included OS and efficacy by tumor PD-L1 expression. Results: In the N+I Q12W and N+I Q6W cohorts, respectively, 42% and 31% of pts experienced grade 3–4 treatment-related (TR) AEs; 18% in each cohort discontinued due to any-grade TRAEs. The most frequently reported any-grade TRAEs were pruritus (26%) and diarrhea (21%) with N+I Q12W, and fatigue (26%) and diarrhea (23%) with N+I Q6W. There were no TR deaths. N+I showed promising efficacy (table). While efficacy was enhanced with increasing PD-L1 expression, activity was noted in pts with <1% PD-L1 (table). Of 6 complete responses (CRs), 3 were in pts with <1% PD-L1. Conclusions: 1L therapy with N+I demonstrates a manageable safety profile and promising, durable efficacy (including pathological CRs) in adv NSCLC; efficacy was enhanced in pts with ≥1% PD-L1 tumor expression. Longer follow-up data, including 2-yr OS and characteristics of long-term survivors, will be presented. Clinical trial information: NCT01454102. [Table: see text]

Abstract
e18292 Background: PD-1 inhibitors such as nivolumab and pembrolizumab have demonstrated efficacy in numerous metastatic cancers. However, these drugs are also some of the most expensive and can have severe adverse side effects. However, most available data comes from clinical trials rather than patients treated in clinical practice as standard-of-care. This study reports the incidence of severe toxicities in a number of cancer types and estimates the per patient cost of managing these toxicities. Methods: All patients treated with nivolumab or pembrolizumab between January 1, 2014 through April 30, 2016 were identified at Moffitt Cancer Center (nivolumab N=74, pembrolizumab N=134). Toxicities occurring during or within 2 months of stopping treatment were identified and graded using the CTCAE 4.0 criteria. A cost of care analysis was performed comparing patients with Grade 3-5 toxicities to patients with Grade 0-2 toxicities. Results: The most common severe toxicities were anemia, dyspnea, dermatitis, hepatitis, and renal failure (Table 1). The average cost of care for patients experiencing Grade 3-5 toxicities was $640 and $4,784 higher than those without toxicity in nivolumab and pembrolizumab, respectively. Conclusions: Primary cost drivers differed between the two drugs with outpatient visits and additional pharmacy costs driving nivolumab cost while inpatient stays and radiation therapy drove costs with pembrolizumab. The large difference between the toxicity cost of each group could be due to the heterogeneity of cancer types treated with nivolumab versus primarily melanoma in the case of pembrolizumab or the smaller sample size of nivolumab patients.

Abstract
93 Background: Recently approved PD-1 inhibitors such as nivolumab have demonstrated clear efficacy in metastatic melanoma and other cancers, but also come at a high cost and with the potential for severe side effects. However, most of the data available comes from clinical trials rather than patients treated in clinical practice as standard-of-care. This study reports the incidence of severe toxicities in a number of cancer types and estimates the per patient cost of managing these toxicities. Methods: Patients with metastatic melanoma, non-small cell lung cancer, renal cell carcinoma, and Hodgkin’s lymphoma treated with nivolumab between January 1, 2014 through April 30, 2016 were identified at Moffitt Cancer Center (N=74). Toxicities occurring during treatment or within 2 months of stopping treatment were identified by a chart review and each toxicity graded using the CTCAE 4.0 criteria. A cost of care analysis was performed to estimate the cost of serious toxicities (Grade 3-5) compared to a control group who experienced no or minor adverse events (Grade 0-2). Billing data was used to estimate the mean cost of care for each group. Costs were subcategorized by service line, e.g., pharmacy costs, radiology, laboratory services. Results: The most common severe toxicities were anemia, dyspnea, renal failure, colitis, fatigue, and pneumonitis (Table 1). The average cost of care for patients experiencing grade 3-5 toxicities was $2,036 higher than those without toxicity. Conclusions: The incidence of toxicity in our population was similar to that reported in clinical trials. Costs were higher for patients with toxicities, driven by additional outpatient care (19% higher cost per patient) as well as additional pharmacy costs (22% higher per patient). Though small in comparison to the cost of nivolumab, over $6,000 per dose, these costs should not be dismissed, particularly when performing cost effectiveness and value research. [Table: see text]
